【python】接口自動化測試中，如何校驗json返回數據的格式是否正確

校驗json返回數據格式是否正確需要用到jsonschema

首先進行安裝

pip install jsonschema

示例

from jsonschema import validate

result = {
    "code" : 0,
    "name": "中國",
    "msg": "login success!",
    "password": "000038efc7edc7438d781b0775eeaa009cb64865",
    "username": "test"
}
#校驗數據格式設定
schema = {
    "$schema": "http://json-schema.org/draft-04/schema#",
    "title": "test demo",
    "description": "validate result information",
    "type": "object",
    "properties": {
        "code": {
            "description": "error code",
            "type": "integer"
        },
        "name": {
            "description": "name",
            "type": "string"
        },
        "msg":
        {
            "description": "msg",
            "type": "string"
        },
        "password":
        {
            "description": "error password",
            "maxLength": 20,
            "pattern": "^[a-f0-9]{20}$",  # 正則校驗a-f0-9的16進制，總長度20
            "type": "string"
        }
    },
    "required": [
        "code","name", "msg", "password"
    ]
}

# validate校驗, 跟assert斷言一個意思
validate(instance=result, schema=schema)

輸出為

 

因為password長度超過了我們校驗中限制的最大長度20
